ed to swing toward and from each other within defined limits. 1

The uppermost table shown on the drawing likewise consists of two units. Referring to one of said units, it consists of two upright supports 26 having across support 22. Sup-.

' ports 26 are pivotallyemounted tocross beams '14 and', preferably with saidpivot18 ,950

that supports 24 and 26 will swing on a com mon axial line indicated pivot. 18,;and

uprights 240 and 260 willfswing on a"common pivot 19. The upright supports shpuigll be; assembled with relation to each other so that 1 the longer uprights. are, onthe'outside; of the shorter ones, and the cross supportsshould be I attached on the sides of theuprightsupports facing thecooperating' cross supports. The

. lengths of the uprights of each-pooperating unit, and the spaced distancefro'm the cross supports to the pivotal mounting of each! upright on said cooperating units should be the same.

a and. pedal 341 is at the other end. 'Byrmeans erating units are standingvertically.

It is noted that the operative position of :the table formed byany two units is had by swinging said cooperating-units to positions .where the cross supports are a spaced distance apart,which in the drawing is shownto be when the upright-supports of said coop- 'The means'forswingingthe movable tables into, and out of op rative relation with r the nailing device is as follows:v a g Upright support 26'.has an extension 27 below'pivot 18 to which arm '32-is attached at an angle thereto. A rod 33 pivotally con-- nects arm 32 with a pedal lever 34. The

fulcrum 340 is at one end of pedalle-ver 34,

of-pedal 341, uprights 26 may be operated to orfrom a vertical position. I To simultaneously move upright 260'to a vertical'position, rod 59 pivotally connects extension 27 and uprightsupport260, extending from a point on upright 260 a spaced distance above pivot 19, to. a point on extension a' spaced' distance below pivot 18. y 1 A compression spring 56 encircles rod 59. A springstop 5'5 iszattached to the rod 59, and a spring stop 58 ,is' attached to crossbeamf1'4.

.lVhen lever 34 I is depressed sprin 56 is "compressed, and when lever 34 is released, the tensionof spr ng-'56 draws s'aidconnectedunits j of the table into operative relation. f

, To .hold "the table in inoperative. position acatch or hook 36-;is providedand attached to the base of the device, and is adapted to hold the pedallever in, depressed position.

Whenthe leveris' released from' the. catch," compression spring 56 will return thet able,

[' The means for moving the intermediate table into and out of-operative position is similar in all respects to the means described for moving the highertable' into and out ofoperativeposition, except that the pedal tllere fore-is on the opposite sideof the frame. The

- parts shown on the drawing to accomplish said purpose consists of the extension 53 to upright 240, rod 49 connecting extension 53 to upright 24, compression spring 46,- spring stop attached to rod 49, spring stop 48 encircling rod 49 and attached to crossbeam 14,

pedal 39, connecting rod 60, and catch 38.

. Itis also noted thatthe permanent table is adapted to form a stop in the movement of the adjustable tables so that the units form- ;ing the adjustable table cannot move toward each other beyond the vertical position. By this arrangement of elements, when the pedal lever 34 is released "from its catch 38, the cooperating units forming the table will move toward each other until in a vertical position and be stopped by permanent table bars 17 and 170., This isthe operative position for the table. By depressing the lever. the '00- I operatingiunits move apart and to an oblique position, thus placing thetable in inoperat ve position and, out of the way of the lower tables which maybe in operative position,

In said drawing 50 and 51 represent the lower portions of thedevices for driving the nails These are shown to illustrate the relation between the boxnailing tables and-said nail driving device. In the machine as illustrated-the fixed table is vusedto support the the. nailing device positions it on the box.

This adjustment will be the subject of another application for Lettersv Patent; n In the drawing I have shown a box being assembled in" which 61 and 610 represent the ends, 62 the side, and 63 the bottom; i

When one side of the box is assembled with the endsandi nailed thereto, the box is then ai ready to be'pos'itioned on 'an upper table for placing the bottom thereon. QThe footlever is released and the cross' beams on the two units forming the table yieldinglyengage the ends of the boxby means of spr1ng 5,6. The

box form. is then pulled forward and the box tallynear thevfront end of the cross supports 22'and 220 forming'thetable. iThe movement in pulling?" the boxforn forwardbver the, projections servesto rock thebox form and throw the under edge thereof on a level with' the top of the table. When the form is raised on said; level spring pressure from spring. 56brings the table assembly against the permanent table usedfas a stop, and di- 'rectly under the box ends, which then acts as a" support for the box ends; The bottom boards 7 are then assembled with. the ends and "ends are engaged by two pins orfprojections 4 40 and 400' extending inwardly and horizonv eiav sasas nailed. The foot lever is then depressed, Whichmoves the upper table in inoperative position in which positionthe lever can be; locked by catch 36 and thepartlyfinished box is'then dropped to the lower tablewith-fithe unfinished side uppermost, in which position the shook is assembled; therewith andnail'ed,

It is noted thatin'the accompanying draw- 7 ing there arebut two n ailing devices shown.

This form ispreferred becauseit is easier to drive the nails selectively as to number i and ing means as well as in the preferredform I j have disclosedyin the drawing; Modifications of thebox'nailing table unitscan' be Vrnade by having one upright pivotedsupport v V p .1 V f eaclrfpart' cofisistingzogfiian pright. member ii pivotail'lyj mounted*at iorreizendqthereofgand i rhaving vcross memberattachedcad acent-ao v rthe othenendaofwzsaidaupright,isaidupivotalf I: mounting adapting theqiuirit,partsstoirloe mioasd toward'and'xfromleachxother;toapjosi Y 7 U :tion.irl npleltativezrelationwvithwthe:naihngV if fidevice and 51130 positions ::in :{inoperative instead oftwo; a a
